Gene, our water has zero minerals and is so soft and low in pH, it
too has side effects if not remineralized before drinking as the
sole source of water.
Roxanne, you may want to bottle and sell that water.
Seriously, what is the source? Many Ozarks' so-called springs are
simply outlets for discrete rainfall collection depressions and have
not run through karst.
You have access to water testing equipment. Check the pH of your rain
and that of your house water. Perhaps there are other chemicals that
would show a correlation or disconnection, and you will have a good
idea of what you are getting. If you have multiple springs, check
several.
And, yes, I know that certain minerals--selenium comes to mind--that
exist in higher-than-usual proportions appear to create specific
health benefits.
I have been using distilled water for about thirty-five years. I will
be 73 years old in two weeks. I have no known negative organic health
conditions.
